+12V2DC, +5VDC and +3.3VDC
voltage rails. Active only when the PSU
tester is in standalone mode (Disable in
Inline mode).
Measurement
Voltages:
+12V1DC, +12V2DC (12V CPU),
+5VDC, +3.3VDC, +5VSB, -12VDC,
+12VDC PCIe
Currents:
+12V1DC, +12V2DC (12V CPU),
+5VDC, +3.3VDC, +5VSB, +12VDC
PCIe, +12VDC SATA, +5VDC SATA.
+3.3VDC SATA
Ripple:
+12V1DC, +12V2DC (12V CPU),
+5VDC, +3.3VDC
Timings:
Power-on Time (T1), Rise Time (T2),
PWR_OK delay (T3) and Power-down
warning (T6)
Minimum slew rate and Ramp up:
Check smooth and continuous ramp up
of +12V1DC, +12V2DC (12V CPU),
+5VDC, +3.3VDC.
Power Sequencing:
Check +12VDC and +5VDC against
+3.3VDC during power up to ensure
they are equal to or greater than the
+3.3VDC.
